A large shaft on a corner of the road just to the north of, and below Alisas. Road workings have left a slope of rubble down into the first part of the shaft. At the base, about 30m down, it is possible to throw rocks into a continuation where they seem to fall about 40m into a chamber. With the position of the site, it must have been descended before by other groups, although no signs were noticed.
The shaft was descended over Easter 2004. A short horizontal section leads to the top of a 47.3m drop in a choked shaft with water sinking in the floor. A parallel shaft entered part way down ended at the same depth when investigated in November 2014.
Further up the road, on the ground within the road hairpin there are a number of other sites which also take water: 2035, 2036 and 2037.
Dowsing in July 2011 failed to find any reactions on the road below all these sites. A summary of the dowsing results can be seen here.
Over Easter 2018, optical brightener was injected into this site and detected between 2 and 3 days later at Fuente Aguanaz (in flood conditions). Other caves checked for OBA included Comellantes, La Riega and Wild Mare. These all proved negative. (Details of the water trace can be found here.)
